Embodiment 1a

[0035] A concrete anti-radiation coarse aggregate, which is composed of the following raw materials in parts by weight:

[0036] 100 parts of serpentine acid leaching residue;

[0037] 20 parts red mud;

[0038] Barite powder 16 parts.

[0039] The preparation method of the above-mentioned concrete anti-radiation coarse aggregate, after fully mixing serpentine acid leaching slag, red mud and barite powder, obtains an aggregate body with a particle size of 5 mm through granulation, and then aggregates the body in Soak in the cement slurry for 5 seconds, then autoclave for 2 hours, then soak in the cement slurry for 5 seconds, then naturally cure for 48 hours to obtain concrete radiation-proof coarse aggregate.

Embodiment 1b

[0041] A concrete anti-radiation coarse aggregate, which is composed of the following raw materials in parts by weight:

[0042] 130 parts of serpentine acid leaching residue;

[0043] Red mud 25 parts;

[0044] Barite powder 10 parts.

[0045] The preparation method of the above-mentioned concrete anti-radiation coarse aggregate, after fully mixing the serpentine acid leaching residue, red mud and barite powder, granulating to obtain an aggregate body with a particle size of 10mm, and then the aggregate body in Soak in the cement slurry for 10 seconds, autoclave for 2 hours, soak in the cement slurry again for 10 seconds, and then naturally cure for 48 hours to obtain concrete radiation-proof coarse aggregate.

[0046] The strength of the concrete anti-radiation coarse aggregate of embodiment 1a and embodiment 1b is as high as 87-94% (same particle size) of natural coarse aggregate.

Abstract

The invention provides concrete anti-radiation coarse aggregate, an anti-radiation heat insulation plate comprising the aggregate and a preparation method of the anti-radiation heat insulation plate.The method comprises the steps of preparing the concrete anti-radiation coarse aggregate from serpentine acid-leaching slag, red mud and barite powder, and then preparing the anti-radiation heat insulation plate in a four-layer structure. The heat insulation plate has performance such as heat insulation, sound insulation, flame retardance and light weight.

Description

technical field [0001] The invention relates to the field of concrete, in particular to a radiation-proof thermal insulation board. Background technique [0002] With the rapid development of modern science and technology, an invisible and intangible source of pollution has attracted increasing attention from all walks of life, which is electromagnetic radiation known as the "invisible killer". Today, the use of more and more electronic and electrical equipment makes electromagnetic waves of different frequencies and energies flood every corner of the earth and even the wider universe. For the human body, a good conductor, electromagnetic waves will inevitably pose a certain degree of harm. [0003] At present, there have been many researches on radiation-proof concrete, and the research focus is only on the radiation-proof performance, which cannot meet other performance requirements, such as heat preservation, heat insulation, sound insulation, flame retardancy, light wei...
